The Effect of Spring System Design on Scavenging of Two Stroke Single Cylinder Spark Ignition Free Piston Linear Engine

Abstract

To increasing the efficiency research a single cylinder linear engine with spring system has been done. Issues raised in the study was the analysis of air flow into the combustion chamber in a single cylinder linear engine, with a spring system for its return cycle. Solidworks has been used to design and simulation as well. This study compared the fluid flow in the combustion chamber between the conventional engine and linear combustion engine. The parameters used are the engine speeds 1000 rpm, 4000 rpm and 4500 rpm. The speeds is chosen because has been predicted that the inlet port on the linear engine can not work properly. Results of analysis that has been done appears average pressure of conventional has a higher value than the linear combustion engine. The same thing happened in velocity, in the average value of the conventional engine is higher than the linear combustion engine.

Prediction Performance of Two Stroke Semi Free Piston Diesel Engine with Dual Piston System

“…The design of a linear engine can reduce the frictional force received and consequently can improve performance such as power, torque, and fuel consumption can be better. [1,2] The difference in working principle between linear engines and conventional engines lies in the return cycle to the top dead centre [6]. In conventional engines is using the basic mechanism of the crank rotation system.…”
